openejb - new feature to create mbeans?

[Romain Manni-Bucau]

Hi,

what do you think about https://issues.apache.org/jira/browse/OPENEJB-1430 ?

it is a first patch version i didn't really test it in something else than
junit test but i think it can be nice to integrate it into our preferred
container ;).

To summarize the idea: i took an abandonned jsr which wanted to create a
standard inspired from spring annotations to create MBean.

For the user it is simply annotation to add to a simple java class (not a
pojo :p).

Here an example:

@MBean
@Description("descr ;)")
public class MyNiceMBean {
    private int i = -1;

    @ManagedAttribute @Description("just a value") public int getValue() {
        if (i < 0) {
            return 2;
        }
        return i;
    }

    @ManagedOperation public String returnValue() {
        return "yes - no";
    }

    @ManagedAttribute public void setValue(int v) {
        i = v;
    }
}

In this patch i used a system property to detect mbean to register (i
preferred to avoid to scan for it)... but it can easily be improved :).
